The Effect of Problem Based Learning Model with Vee Diagrams on Science Competence of Class VIII Public Middle School 3 Tambusai Based on Learning Motivation

Abstract

This research is motivated by the implementation of this PBL model, especially in class VIII at SMPN 3 Tambusai. This is evidenced in the realm of attitude and knowledge of students is still low, seen from some students who just sit quietly and do not want to ask questions, lack the courage to put forward ideas or ideas, record explanations if asked, make steps pratikum activities told by teachers, some students in the group are just waiting for the results of their friends, still unable to present the results of the practice in front of classmates. This fact shows that students are still passive in carrying out learning activities because students are still dependent on the teacher. Student learning outcomes in the realm of knowledge for Biology science subjects are not optimal. Efforts to overcome these problems by applying a scientific-based learning model with amodel Problem Based Learningwith vee diagramsand learning motivation. This study aims to determine the effect of PBL models with vee diagramsand motivation on the learning potential of VIII grade students of SMP Negeri 3 Tambusai. This type of research is quasi-experimental with 2x2 factorial design research design that is distinguished by groups of students with high motivation and low motivation for both classes of samples. Research instruments in the form of written tests for knowledge competencies and non tests for attitude competencies and skills. Analysis of the data used is two-way Anova and t test. The results of this study prove that the learning competency of students who apply the PBL model with vee diagramsis better than students who apply the PBL model and there is no interaction between the learning model with the learning motivation of the students' knowledge competence.
